The companies first announced a collaboration in January when they agreed to team up on the launch of an online grocery service in Japan and the sale of e-readers, audiobooks and e-books from Rakuten-owned Kobo in the U.S. That e-grocery service — Rakuten Seiyu Netsuper — rolled out in October, and now the duo have launched the Walmart Rakuten Ichiba Store to help Walmart grab a slice of Japan’s e-commerce market, which is estimated to be worth 16.5 trillion yen ($148 billion) per year.

The store, which sits on Rakuten Ichiba — Japan’s largest e-commerce store — will cover 1,200 “U.S. branded” products that include clothing, outdoor items and kids toys. Walmart will fulfill orders in the U.S. and they will be sent by air to Japan where Rakuten will use its e-commerce smarts to deliver them. There’s no word on how long the process will take, but it will include shipping cost, duties and taxes in the final price.

The move is an interesting one for Walmart, which has struggled in Japan for some time.

Partnering with Rakuten, the $10 billion e-commerce giant that also covers financial services, travel, mobile and more, is a smart way to take a bite out of Japan’s online market with risk or exposure. Though it does have its limits. Amazon, Walmart’s big domestic rival, is taking on Rakuten directly, by contrast, and seeing some success albeit at a high cost of investment.
